Application works fine even with microloader if I don't deploy built (by Sencha Cmd utility) production code, but I didn't adapt to Sencha Cmd without reason. I want my codes to be deployed concatenated into one, minified (app.js) source file.

Indeed I did so, but that was not a case. In fact I'm developing in CoffeeScript instead of pure JS and generated code is not always the one, Sencha dependency analyzer dreams of. More over I have found, that concatanated code is more restrictable in the means of proper usage of ST. I made it semi working right now, but still couple of screens don't work yet.

Thanks for your help.
